Interior

The main vent in the rear of the chassis is covered by a large dust filter - perhaps an odd inclusion in an open-air case, especially as it will only come into use if you decide to draw air though this rear section and out over a radiator mounted on the side. This would mean the front of the fans wouldn't be pointing outward, however, which goes against the usual completed build photography of all of Thermaltake's Core cases.

There's a reasonable amount of scope for a massive storage setup, with three dedicated 2.5" mounts next to the radiator mounts plus two 3.5" trays included for optionally adding two hard disks inside the chassis on a large steel plate. Beneath this are two tool-free mounts for either SSDs or hard disks, so we doubt anyone will be left wanting here.

Cable routing is a strong point for the Core P90. There are plenty of holes, some of which are grommeted, and the cavernous interior means that stowing the excess out of sight is easy. In terms of cooling, the case is clearly geared towards water-cooling, and with Thermaltake offering its own range of water-cooling gear these days, it's in a very rare position of being able to offer DIY water-cooling hardware, case, and even a PSU. 

The fan mounts support four 120mm fans or three 140mm fans with 480mm and 420mm radiators slotting in respectively as a result. There's essentially no depth limit either with space for a second row of fans on a 60mm-thick radiator either outside or inside the chassis, while mounts are included for pumps and reservoirs too. There's other paraphernalia for mounting the graphics card vertically and for securing the PSU.
